//cant figure out what is wrong?? any ideas?

What's your problem exactly? What error message?

Just looking at this code, it probably won't compile, because you use "system()" without including the header (<cstdlib>) that declares it.
Try "#include <cstdlib>"

Since you're using super-duper C++, perhaps instead of 'system("pause")', try something like "cin.get()" Same effect.
